Isolated Great Saphenous Vein Thrombus Is Associated with High Rates of Complications regardless of Management

Isolated GSVT tends to affect patients with hypercoagulable states, prior venous thromboembolism, malignancy, or recent surgery. Management is heterogeneous, and type of treatment does not seem to affect outcomes. Patients with GSVT have significant risk of persistent symptoms, recurrence, DVT, and PE. GSVT within 5 cm of the SFJ seemed to be associated with an increased rate of PE. GSVT more than 5 cm from the SFJ seemed to be associated with propagation/new SVT. Proximity to the SFJ did not impact occurrence of DVT.
